<p class="level0">CURLcode curl_easy_setopt(CURL *handle, CURLOPT_DNS_SERVERS, char *servers); <a name="DESCRIPTION"></a><h2 class="nroffsh">DESCRIPTION</h2>
<p class="level0">Pass a char * that is the list of DNS servers to be used instead of the system default.  The format of the dns servers option is: 
<p class="level0">host[:port][,host[:port]]... 
<p class="level0">For example: 
<p class="level0">192.168.1.100,192.168.1.101,3.4.5.6 <a name="DEFAULT"></a><h2 class="nroffsh">DEFAULT</h2>
<p class="level0">NULL - use system default <a name="PROTOCOLS"></a><h2 class="nroffsh">PROTOCOLS</h2>
<p class="level0">All <a name="EXAMPLE"></a><h2 class="nroffsh">EXAMPLE</h2>
<p class="level0">TODO <a name="AVAILABILITY"></a><h2 class="nroffsh">AVAILABILITY</h2>
<p class="level0">This option requires that libcurl was built with a resolver backend that supports this operation. The c-ares backend is the only such one. 
<p class="level0">Added in 7.24.0 <a name="RETURN"></a><h2 class="nroffsh">RETURN VALUE</h2>
<p class="level0">Returns CURLE_OK if the option is supported, CURLE_UNKNOWN_OPTION if not, CURLE_NOT_BUILT_IN if support was disabled at compile-time, CURLE_BAD_FUNCTION_ARGUMENT when given an invalid server list, or CURLE_OUT_OF_MEMORY if there was insufficient heap space. <a name="SEE"></a><h2 class="nroffsh">SEE ALSO</h2>
